When all of us first start out with sparring it would be quite easy to think wow this hurts.
So it's very important that you get the right partner to train with in the beginning who encourages you when you do something right and guide to you when you do something wrong but also without realising if your partner is hitting a little bit hard you will close up and not relax. So this will stop you from learning and trying new techniques because you're afraid of getting hurt. So if you can overcome your ego, ask your partner would you mind going to little bit lighter until I find my feet. You sparring partner is going to become your best teacher so choose them wisely.
